Abstract

In a radio communication system in a mobile to mobile call with one good (AMR 102 ) and bad (AMR 515 ) radio link, the good radio (AMR 102 ) link is forced by the poor (AMR 515 ) link to use a more robust AMR coded mode (AMR 515 ) and thereby using excessive power ( 232 ). A capacity loss in such system is avoided by adjusting the power level ( 212 ) for the connection with the good link (AMR 102 ).
